本研究旨在探討臺東縣國小六年級學生父母的婚姻配對現況與封閉性，採用2015年科技部「臺灣東部教育長期資料庫之建置」三年期計畫第一期之臺東資料庫學生卷樣本，藉由百分比交叉表及對數線性之統計分析方法獲得資料。臺東縣國小六年級父母（N＝369）在族群婚配的百分比交叉表中，指出本省閩南及原住民族於嫁出或娶入表的族群婚配表內，皆呈現較高比例的婚配封閉性；但於進一步的對數線性分析表中，原住民內婚的現象較其他族群明顯，而本省閩南、本省客家及外省人的婚姻封閉性很低，顯見同屬漢族的閩南、客家及外省三大族群之接觸日益頻繁，族群間之文化隔閡與交友界線已逐漸消失，有助於促進跨族群婚配的現象。而臺東縣國小六年級學生原住民父母的婚配族群上，百分比交叉表分析發現，多數原住民皆以同族群之異性為主要婚配對象，而在後續的對數線性分析中更發現，原住民各族之間的族群內婚現象有明顯的族群差別，以達悟族、布農族、排灣族、魯凱族內婚機會較高，阿美族、卑南族的內婚機率較低，其主要受到各原住民的族群文化差異與居住地空間隔離效果強弱之影響。

This study aims at investigating the current situation and insularity of the nuptial matching of sixth graders parents and that of indigenous parents in Taitung County. In this study, student questionnaire samples used in the Taitung Database from the first phase of the three-year project initiated by the Ministry of Science and Technology in 2015, “Construction of the Eastern Taiwan Education Panel Survey,” was examined and data were obtained by means of the statistical methods of percentage cross tabulation and log-linear analysis (N＝369).The percentage cross table of ethnic marriage among the parents of the sixth graders in Taitung County shows that in the ethnic marriage table of the marriage table, both Taiwanese Hokkiens or indigenous people exhibited a higher ratio of nuptial insularity. In the log-linear analysis table, the phenomenon of endogamy was more conspicuous among indigenous people than in other ethnic groups, while the nuptial insularity of Taiwanese Hokkiens, Taiwanese Hakkas and Mainlanders was very low, revealing that the contact among Hokkiens, Haakas and Mainlanders, all belonging to the Han ethnicity, has become increasingly frequent, and the cultural barriers and friendship boundary among different ethnic groups are fading; the increase in ethnic homogeneity helps promote interethnic marriage.
